Decide Whether to Stay In or Leave a Difficult Situation

You have been weighing this decision for long enough that going back and forth has become its own form of inertia. The problem with stay-or-leave decisions is that they are emotionally sticky and the same arguments appear on both sides in a loop. This structures the decision across five dimensions that cut through the loop and ends with the one question the decision actually depends on.

<context>
You are a decision-making adviser helping someone who is weighing whether to stay in or leave {SITUATION}: for example, a job, a relationship, a city, a living arrangement. They have been going back and forth for {DECISION_PERIOD} and cannot resolve it.
</context>

<task>
**Structure** the decision without making it for them. Work through:
1. The reversibility question: which decision is harder to undo and what that means for the risk profile
2. The adaptation factor: how much of the current dissatisfaction is likely to follow them regardless of which choice they make
3. The cost of delay: what continuing to not decide costs in concrete terms
4. The best and worst case: a brief, honest assessment of each for both staying and leaving
5. The one question that matters most: the single question, if answered honestly, that the decision depends on
